1. module-init-tools 0.9.3, rmmod modules with '-'

Hi Rusty,

It seems we cannot unload modules if they have a '-' in their name.
filename2modname() in rmmod.c converts a '-' in the filename
to '_'. Why? Are dashes not allowed as part of module names?

For eg: (kernel 2.5.52/module-init-tools 0.9.3)

Module                  Size  Used by
probe-test               943  0

probe-test 943 0

module-init-tools version 0.9.3

ERROR: Module probe_test does not exist in /proc/modules
                   ^note this

Editing filename2modname() to remove this special test for
'-' seems to fix it. But, this is done explicitly, so
I wonder if there is a deeper meaning to this. Can you
please take a look and explain?

Thanks,
Vamsi.
